Soon we can try asrock mb with 14 pci-e Cool

their last demo got burned, i hope they can fix it and come with somethign about the restriction of window and 8 gpu, otherwise would be pointless to have 14 slot if you can't use six of them

8 GPUs on Z270 Prime was easy.

I have not seen anyone that has gotten a gpu to work via an M. 2 to PCI-e adapter. The one I got from ebay did not and I was refunded. Not even if the system has only one gpu installed. So except for people that has modified custom MB I don't know of anyone who is has gotten more than 7 rx cards working.

They work.

Of course you enter the problem with power supplies at a high enough rating, in which case it's usually easier to build two rigs with more affordable components etc.


A 9 card RX 4XX/5XX rig uses a lot less power than the old R9/280X 6 card rigs from a few years ago. A server PSU or dual PSU setup is also an option.

The ASUS Z270 PRIME A / AR is verified to do 9 cards, 264 MH/s per rig if you add M.2 to PCI-E expansion adapters.

the M.2 is normally shared with one of the PCI-e slots on the intel 2xx chipset.  You get one or the other.

Does anyone testing to run more then 7 RX 4xx gpus on B250/H270/Z270 motherboards?

no   7 is the basic limit.

I read on this group people that run 8 with z270 chip, with m2 to pcie or usb extender

yep  but that is not a basic setup.

Some have done  up to 8 with  pcie splitter

But 7 is the basic limit.

And most will tell 5 or 6 makes more sense.
